Most shelf space is taken up by children's books.

Explanation:

Decimals, fractions and percents are all different ways of expressing the same value. They are interchangeable.

You cannot compare values which are in different forms, so you need to convert. Decimals are usually the easiest for comparisons.

#0.3 = 0.3" "larr# already in decimal form

#25% = 25/100 = 0.25#

#7/20 xx5/5 = 35/100 = 0.35#

#0.25 < 0.3 < 0.35#

Most shelf space is taken up by children's books.
